Earth’s ice is melting. As icebergs break away from glaciers and melt away, the fresh meltwater mixes into its saltwater surroundings. However, icebergs do not exist in isolation. In Greenland, for example, jammed collections of icebergs and sea ice make up what are known as mélanges. Determining how these pieces of ice are affected by the meltwater of their neighbors is key to understanding—and eventually reducing—global ice loss.
